How can you move forward with somebody who wouldn't accept correction? You just shrug your shoulders and think, "Oh well. There's no teaching the arrogant ignorant." That's what sensible people who don't want to waste their time do.
Me, however, I make a YouTube video on the subject and rope my daughter into the silliness with me. We did have fun making the video. It was particularly challenging because we made an incorrect assumption (that we could do a voice-over or dub using the YouTube video editor). We experimented with a few free video-making programs downloadable from the Internet before we settled on VideoPad.
And this is what we ended up with.
So now that you know the difference between a French braid and a Dutch braid, you can now live a happy life, rule the world, or smirk knowingly the next time some arrogant ignorant tries to incorrectly school you on this very important distinction. :D
